Rom. 14 and 1 Cor. 10 clearly state that the stronger are to defer to the weaker in matters of conscience, without casting judgment upon them. So all this banter about how Rom. 14 gives "me" the right to do what to do is a clear violation of that principle.
Love would say, "If attending the theatre causes my brother to offend, then I will not attend the theatre as long as the world stands."
Very true, but that sword cuts both ways.
"The man who eats everything must not look down on him who does not, and the man who does not eat everything must not condemn the man who does, for God has accepted him. 4Who are you to judge someone else's servant? To his own master he stands or falls. And he will stand, for the Lord is able to make him stand."
And If I eat, Rom 14 clearly indicates that those who do not are not to speak evil of it, since it is an extrabiblical issue. We are speaking specifically of the act of attending a movie at a theatre. Not going to see a wicked movie, that would be clearly covered by other concrete Biblical principles. Lets use for example, Finding Nemo as the movie we are attending.
IF the content is wicked, its wrong
IF a brother is caused to sin (that is what Paul means by causing someone to offend) by my actions its wrong - see more below
IF I am placing the theatre and its entertainment in a place higher than God in my life, its wrong
However,
IF someone is "offended" in the modern sense of the word, its really their issue, they need to get over it.
I do not try to convince people to come see movies with me if they have a problem with it. I do not have any problem telling them what movies I went to see, and explaining why I think the movie is worthy of my time. If they are assuming the worst, the problem is not with me, its with them. My actions cannot be used as an excuse to sin. The problem of causing a brother to sin would come into play if I were attempting to convince someone to go even if their conscience would prohibit them. My options in that case are to either abstain myself, clearly indicate that their position is one that they must embrace given the state of their conscience on the particular issue, or assist them in aligning their conscience with the Word of God, which IMO, if they feel the theatre itself is wicked, they have done what paul warns about in Ephesians and have gone beyond the text, or more likely, have been indoctrinated by someone who did so.
"Therefore do not go on passing judgment before the time, but wait until the Lord comes who will both bring to light the things hidden in the darkness and disclose the motives of men's hearts; and then each man's praise will come to him from God.
Now these things, brethren, I have figuratively applied to myself and Apollos for your sakes, so that in us you may learn not to exceed what is written, so that no one of you will become arrogant in behalf of one against the other.
For who regards you as superior? What do you have that you did not receive? And if you did receive it, why do you boast as if you had not received it?"
Either way, my attendance of the theatre is not the issue.
If I determined that someone in my sphere of influence was quenching their conscience in order to be involved with an activity that I have no problem with, I would respond in love, and attempt to help them deal with their conscience, either by adjusting their underlying principles to align with scripture, evaluating my own actions, or by indicating to them that they need to be acting in faith, and cannot go against their conscience, even if I deem the action ,by virtue of studying the Word, to be innocent.
Then you should also respect our right to say they have no redeeming value and they are a waste of a Christian's valuable time, which time we have been admonished to redeem.
No, That clearly goes beyond what you can say Biblically. You have every right to determine that for your own life, but I will have to account for what I do with my life before God, you really have nothing to say about that. Besides the fact that its just plain incorrect.
